Abstract

Procédé de xénotransplantation d'organes, de tissus, de cellules ou d'éléments non viables, ce qui limite ou empêche des rejets provoqués par des anticorps, y compris un rejet hyperaigu. Ce procédé consiste à préparer des animaux transgéniques exprimant au moins une enzyme masquant ou diminuant le niveau du déterminant antigénique de Galα(1,3)Gal et au moins un inhibiteur de complément, tel que CD59, DAF et/ou MCP. Ces animaux transgéniques exprimant à la fois une enzyme de diminution du déterminant antigénique de gal et un inhibiteur de complément posséderont des niveaux masqués ou diminués du déterminant antigénique de gal et seront beaucoup moins susceptibles de produire un rejet provoqué par des anticorps après la transplantation, et l'expression de l'inhibiteur de complément supprimera également l'activation du complément et limitera encore plus un risque de réaction immune grave après la transplantation d'organes, de tissus, de cellules et d'éléments non viables provenant de ces animaux transgéniques. De plus, l'invention concerne des animaux transgéniques exprimant une pluralité d'inhibiteurs de complément ou d'autres protéines provenant d'un locus de gènes au niveau d'un seul site d'intégration. L'invention présente des avantages résidant dans la production d'organes, de tissus, de cellules et d'éléments non viables xénogènes qui peuvent être transplantés efficacement et sans risques à l'homme et présentent une capacité de limitation ou d'élimination d'un rejet provoqué par des anticorps beaucoup plus importante qu'il n'était possible d'obtenir jusqu'à maintenant, ce qui diminuera considérablement la nécessité d'obtenir des organes, des tissus, des cellules ou des éléments non viables à partir de l'homme ou du primate.
